Praise be to Allaah.
If a man dies leaving wealth and leaves behind two wives, a
son and a daughter from the first wife and a daughter and three sons from
the second wife, and his estate was one hundred thousand riyals, then it is
to be divided as follows:
The wives get one eighth, to be divided between them, because
Allah, may He be exalted, says (interpretation of the meaning):
“…their (your wives) share is a fourth if you leave no
child; but if you leave a child, they get an eighth of that which you leave
The children get the rest, with each male getting the share
of two females, because Allah, may He be exalted, says (interpretation of
“Allah commands you as regards your childrens
(inheritance); to the male, a portion equal to that of two females”
When the estate is divided, each wife gets 6,250; each son
gets 17,500 and each daughter gets 8,750.
And Allah knows best.
